Tafoflora paleógena da formação entre-córregos (Bacia de Aiuruoca): arquitetura foliar e paleoclima

The present study aims to analyze the leaf architecture of the Entre-Corregos Formation plant fossils, from the municipality of Aiuruoca, State of Minas Gerais. Based on these foliar architectural features and their meanings as climatic adaptation, the work shows that during the Middle Paleogene (Late Eocene-Early Oligocene), this region had high temperatures and wet weather, and was included into a tropical everwet biome going on to a subtropical summerwet.
